Still puzzled as to Diana's identity, Bruce discovers more about her amongst the data he stole from Lex Luthor. He sees a photograph of her alongside the Wonder Men, taken in Belgium in 1918 during the closing days of World War I. He then makes contact with her via her laptop, sharing extra information that Luthor had on both her and other metahumans, such as the Flash, Aquaman, and Cyborg. Diana is visibly intrigued and shocked at this revelation, as Flash's lightning reminds her of that of Ares, Aquaman reminds her of depictions of Poseidon, while the Mother Box that created Cyborg reminds her of the one she briefly saw back on Themyscira. Diana resolves to take some time to think this revelation over, does not answer Bruce's e-mail, and instead proceeds with her plans to depart Metropolis on a flight back to France, through Turkey.
By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
In Wonder Woman Vol. 1 #204, Diana's powers and costume were returned to her and she is once again reinstated as Wonder Woman. I-Ching is killed by a crazy sniper in the same issue. Later, Diana meets her sister Nubia, who is Hippolyta's daughter fashioned out of dark clay (hence Nubia's dark complexion). Nubia claimed to be the "Wonder Woman of The Floating Island", and she challenges Diana to a duel which ends in a draw. Returning to her home, Nubia would have further adventures involving Diana.
The costs for television advertisements for Wonder Woman are higher in comparison to that of previous DCEU film Suicide Squad. Warner Bros. has spent over $3 million on advertisements for Wonder Woman, whereas they spent $2.6 million on advertisements for Suicide Squad. Ticket selling site Fandango reported that Wonder Woman rounded the final leg of its marketing campaign as the most anticipated blockbuster of summer 2017, according to a poll conducted by 10,000 voters, the biggest survey in company history. Separately, Fandango also found that 92% of people surveyed said that they are looking forward to seeing a film that features a standalone woman superhero, and 87% wished Hollywood would make more women-led superhero films. In May 2017, NASCAR driver Danica Patrick drove her No. 10 car with a Wonder Woman paint scheme at the Go Bowling 400 in Kansas and at the Monster Energy Open in Charlotte.
